Abstract
The simultaneous occurrence of stimulated Raman scattering and optical frequency mixing in LiIO3 at kHz PRF’s (pulsed repetition frequency) has previously been investigated using a two-mirror internal Raman configuration. These simultaneous processes produce multiple visible outputs that are selectable by rotating the LiIO3 crystal. In this paper, the same simultaneous processes are investigated using a three-mirror configuration. It is found that the three-mirror configuration yields smaller average visible output powers, but larger peak powers, than the corresponding two-mirror configuration.
